glDrawRangeElementsBaseVertex is a restricted form of glDrawElementsBaseVertex(). mode, start, end, count and basevertex match the corresponding arguments to glDrawElementsBaseVertex(), with the additional constraint that all values in the array indices must lie between start and end, inclusive, prior to adding basevertex. Index values lying outside the range [start, end] are treated in the same way as glDrawElementsBaseVertex(). The ith element transferred by the corresponding draw call will be taken from element indices[i] + basevertex of each enabled array. If the resulting value is larger than the maximum value representable by type, it is as if the calculation were upconverted to 32-bit unsigned integers (with wrapping on overflow conditions). The operation is undefined if the sum would be negative.
